All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As shown in fig. 1, a simulation operation method provided in an embodiment of the present application may be applied to an electronic device capable of performing data processing, such as a computer or a server. The technical scheme in the embodiment is mainly used for starting the corresponding operation process for processing according to the bit width parameter of each obtained simulation model when simulation operation is performed, so as to obtain a project simulation result of a simulation project.
In a specific implementation, the method in this embodiment may include the following steps:
step 101: and acquiring a simulation project to be simulated and operated.
The simulation project includes a plurality of simulation models, and the simulation model may be a simulation model encapsulated based on a standard protocol, for example, an FMU (Functional module-Up Unit) simulation model encapsulated based on an FMI (Functional module-Up Interface) protocol.
Specifically, the simulation project refers to a simulation system project including various meta-models to be operated, where the meta-models are simulation models.
In a specific implementation, in this embodiment, a simulation project including a simulation model to be operated may be loaded on an implemented simulation platform, for example, an application program of the simulation platform is first opened, a simulation system project including a plurality of FMU simulation models, which is required and has been created in advance, is manually selected on a loading interactive interface of the simulation platform, that is, the simulation project is clicked to open the simulation system project, so as to implement loading of the simulation system project.
Step 102: and obtaining the bit width parameter of each simulation model.
The bit width refers to a data amount which can be transmitted by the memory or the video memory at one time, the bit width parameter refers to a system bit width parameter of the modeling system when the simulation model is modeled, and the bit width parameter of each simulation model may be the same or different, that is, each simulation model may be created based on the modeling system with different system bit widths. Specifically, the bit width parameter may have 16 bits, 32 bits, or 64 bits, etc.
In specific implementation, in this embodiment, after loading a simulation project on a simulation platform, a bit width parameter of each simulation model in the simulation project is obtained, for example, there are 3 simulation models in the simulation project, and the bit width parameters of the 3 simulation models are all 32 bits, or there are 4 simulation models in the simulation project, and the bit width parameters of the 4 simulation models are all 64 bits, or there are 5 simulation models in the simulation project, and the bit width parameter of 2 simulation models in the 5 simulation models is 32 bits, and the bit width parameter of the other 3 simulation models is 64 bits.
Step 103: and judging whether the bit width parameters are at least two, if so, executing the step 104.
Specifically, in this embodiment, the bit width parameter may be classified to obtain the type of the bit width parameter, for example, the bit width parameter of all simulation models in the simulation project may be only one, for example, all simulation models in the simulation project are 64-bit simulation models; or, there may be two bit width parameters of all simulation models in the simulation project, such as 32-bit simulation models and 64-bit simulation models in the simulation project; or, there may be three bit width parameters of all simulation models in the simulation project, and the simulation project has 16-bit simulation models, 32-bit simulation models, and 64-bit models; and so on.
Step 104: and under the condition that the bit width parameters are at least two, starting at least two operation processes, wherein each operation process corresponds to the simulation model with the same bit width parameter, and each operation process is used for carrying out simulation operation on the corresponding simulation model to obtain a project simulation result of the simulation project.
In this embodiment, the operation process refers to an operation activity capable of implementing simulation operation on a simulation project. The simulation operation is to establish an equivalent mathematical model, write a simulation program on a computer, compile and run.
In a specific implementation, in this embodiment, under the condition that bit width parameters of the simulation model in the acquired simulation project are at least two, at least two operation processes are correspondingly started, and the simulation models with the same bit width parameter perform simulation operation by using the same operation process, so that the operation processes are respectively used to perform simulation operation on one or more simulation models with corresponding bit width parameters, and finally, a project simulation result of the simulation project is obtained.
For example, the acquired simulation project includes two simulation models, namely a simulation model with a bit width parameter of 32 bits and a simulation model with a bit width parameter of 64 bits, and two operation processes are correspondingly started, wherein one operation process is used for executing simulation operation on the simulation model with the bit width parameter of 32 bits, and the other operation process is used for executing simulation operation on the simulation model with the bit width parameter of 64 bits, so as to obtain a project simulation result of the simulation project;
or, the acquired simulation project comprises three simulation models, namely a simulation model with a bit width parameter of 32 bits and two simulation models with a bit width parameter of 64 bits, and two operation processes are correspondingly started, wherein one operation process is used for executing simulation operation on the simulation model with the bit width parameter of 32 bits, and the other operation process is used for executing simulation operation on the simulation models with the bit width parameter of 64 bits, so as to obtain a project simulation result of the simulation project;
or, the acquired simulation items include three simulation models, namely a simulation model with a bit width parameter of 16 bits, a simulation model with a bit width parameter of 32 bits, and a simulation model with a bit width parameter of 64 bits, and three operation processes are correspondingly started, wherein one operation process is used for executing simulation operation on the simulation model with a bit width parameter of 16 bits, one operation process is used for executing simulation operation on the simulation model with a bit width parameter of 32 bits, and the other operation process is used for executing simulation operation on the simulation model with a bit width parameter of 64 bits, so as to obtain an item simulation result of the simulation item.
As can be seen from the foregoing solution, in the simulation operation method provided in the first embodiment of the present application, a simulation item to be subjected to simulation operation and including a plurality of simulation models is obtained, and then at least two operation processes can be started under the condition that bit width parameters are at least two by obtaining a bit width parameter of each simulation model, where each operation process in the started operation processes corresponds to a simulation model having the same bit width parameter, and thus each operation process is used for performing simulation operation on the simulation model corresponding to each operation process, so as to obtain a project simulation result of the simulation item. Therefore, whether the simulation models with different bit width parameters exist in the simulation project or not is automatically identified when the simulation operation is started, so that the corresponding operation processes are started for the simulation models with different bit width parameters to perform corresponding simulation operation processing and output project simulation results.
In one implementation, the first operation process of the at least two operation processes started in step 104 is further configured to transmit the operation result to the second operation process. The first process operation result is an operation result obtained by performing simulation operation on one or more simulation models corresponding to the first process operation result by the first operation, and specifically includes the following steps:
the first operation process transmits a first process operation result obtained by the first operation process performing simulation operation on the corresponding simulation model to a second operation process of the at least two operation processes, so that the second operation process performs simulation operation on the simulation model corresponding to the second operation process according to the first process operation result to obtain a project simulation result of the second operation process;
and the second operation process is also used for transmitting the project simulation result of the simulation project to the first operation process.
Further, the first operation process is further configured to output the project simulation result, for example, the first operation process outputs the project simulation result of the second operation process. For example, the first operation process may also transmit the project simulation result to an interactive interface, such as a UI interface, through an interface between the first operation process and the interactive interface on the simulation platform, so as to perform subsequent processing according to the result sent by the first operation process, for example, outputting data such as a corresponding table or an image on the UI interface.
Furthermore, data transmission is performed between the operation processes of the at least two operation processes through a tcp (transmission control protocol).
It should be noted that "first" and "second" in the first operation process and the second operation process are used to distinguish two different master and slave processes, and the project simulation result is generated by the second operation process.
In a specific implementation, in at least two started operation processes in this embodiment, one operation process is used as a first operation process, that is, a master operation process, and the other operation processes are used as second operation processes, that is, slave operation processes, and the first operation process transmits an operation result of the first operation process, which is obtained by performing simulation operation on a simulation model corresponding to the first operation process by the first operation process, to the second operation process through TCP, so that the second operation process performs simulation operation on a simulation model corresponding to the second operation process according to the operation result of the first operation process to obtain a project simulation result of a simulation project, transmits the obtained project simulation result to the first operation process through TCP, and finally, the first operation process outputs the project simulation result of the second operation process.

The method comprises the following specific steps:

The technical scheme in the embodiment is mainly used for starting the corresponding operation process for processing according to the bit width parameter of each obtained simulation model when simulation operation is performed, so as to obtain a project simulation result of a simulation project.
Specifically, the electronic device in this embodiment may include the following structure:

a processor 502 for executing an application to implement: obtaining a simulation project to be simulated and operated, wherein the simulation project comprises a plurality of simulation models; obtaining a bit width parameter of each simulation model; and starting at least two operation processes under the condition that the bit width parameters are at least two, wherein each operation process corresponds to a simulation model with the same bit width parameter, and each operation process is used for performing simulation operation on the corresponding simulation model to obtain a project simulation result of the simulation project.
According to the scheme, the electronic device provided by the third embodiment of the application first obtains a simulation item to be subjected to simulation operation and including a plurality of simulation models, and then starts at least two operation processes under the condition that bit width parameters are at least two by obtaining bit width parameters of each simulation model, wherein each operation process in the started operation processes corresponds to a simulation model with the same bit width parameters, and therefore each operation process is used for performing simulation operation on the simulation model corresponding to the operation process to obtain a project simulation result of the simulation item. Therefore, whether the simulation models with different bit width parameters exist in the simulation project or not is automatically identified when the simulation operation is started, so that the corresponding operation processes are started for the simulation models with different bit width parameters to perform corresponding simulation operation processing and output project simulation results.

Fig. 6 is a flowchart of a simulation operation applied to a 32-bit simulation model and a 64-bit simulation model coexisting in a simulation project according to an embodiment of the present application:
(1) after a simulation system project (namely a simulation project) is loaded in a simulation platform realized by the application, a user starts and starts simulation operation, and the simulation platform preferentially identifies whether a bit width parameter of an FMU simulation model existing in the project is pure 32 bits or pure 64 bits or the coexistence of 32-bit FMU simulation models and 64-bit FMU simulation models.
(2) If the simulation system project is composed of the FMU simulation model with the stored 64-bit width parameter, a 64-bit simulation operation engine process (i.e., a third operation process) is used for performing simulation operation, and the project simulation result is transmitted back to the simulation platform through the TCP, as shown in fig. 7.
(3) If the simulation system project is composed of a pure FMU simulation model with 32-bit width parameters, a 32-bit simulation operation engine process (namely, a third operation process) is started to perform simulation operation, and a project simulation result is transmitted back to the simulation platform through a Transmission Control Protocol (TCP), as shown in FIG. 7.
(4) If the simulation system project is a simulation system project with coexisting FMU simulation models with 32-bit and 64-bit width parameters, after a 32-bit simulation operation engine process (namely a first operation process) is started, the process pulls up a Slave operation engine process (namely a second operation process), so that the Slave process carries out simulation operation on the FMU simulation models with 64-bit width parameters, project simulation results are returned to the first operation process, the first operation process comprehensively processes 32-bit FMU simulation model project simulation results generated by the process and 64-bit FMU simulation model project simulation results generated by the second operation process, and the comprehensively processed project simulation results are returned to a simulation platform in real time through a Transmission Control Protocol (TCP), as shown in figure 8.
(5) After the simulation is finished, if the Slave operation process is started, the Slave process is recovered by the first operation process.
In conclusion, the method and the device perfectly realize the real-time operation of the simulation system when the 32-bit 64-bit FMU simulation models coexist, expand the application range of the simulation platform and provide powerful technical guarantee for the flexible construction of the simulation system.
Therefore, in the simulation operation process, a user can not completely feel the simulation operation difference caused by the coexistence of the 32-bit 64-bit FMU simulation models, the simulation efficiency is greatly improved, and the time for user configuration is greatly shortened.
